UPDATE 1 P.M.: Lewis and Clark County Sheriff Leo Dutton confirmed a man died following a traffic stop in East Helena on Thursday morning.
According to the sheriff, a state Fish and Game officer stopped a vehicle that police were looking for following a reported domestic incident in the Helena Valley.
Dutton said law enforcement officers were negotiating with the man for about a half hour before the man fatally shot himself.
Because the incident is considered an "in custody death," the Montana Division of Criminal Investigation and the Anaconda-Deer Lodge coroner will conduct the investigation.
Dutton said no officers fired their weapons during the incident.
The identity of the man has not been released.
